ANALYSIS OF MICROBIAL COMMUNITY DIVERSITY IN RHIZOSPHERE SOIL OF LILIUM LONGYA WITH ANTHRAX DISEASE AND HEALTHY PLANTS
摘要
Abstract
The rhizosphere microbial community structure is closely related to plant diseases,anthrax is a common and important disease often occurring in the cultivation of longya lily,but there are very few researches on the rhizosphere soil microbial community of anthrax lily.To deeply understand the relationship between lily anthrax occurrence and soil microbial community structure in the rhizosphere,Illumina MiSeq high-throughput sequencing was used to compare the differences in the diversity and composition of rhizosphere soil microbial communities between the diseased and healthy lily.The results show that the richness of microbial community in the rhizosphere soil of anthrax lily decreased and the diversity increased,among them,the relative abundance of Ascomycota and Mortierellomycota in the fungal community increased,the relative abundance of Basidiomvcota and Rozellomycota decreased.Phlogicylindrium,Schizothecium and other genera were the biomarkers of healthy lily,while Fusarium,Saitozyma and others were the biomarker fungi in the rhizosphere soil of anthrax lily.In addition,the relative abundance of Acidobacteria increased,the relative abundance of Proteobacteria decreased,the proportion of Gemmatimonas increased and that of Rhizomicrobium decreased significantly.Therefore,the microbial community structure of rhizosphere soil of longya lily was changed after anthrax infection.This study can play a positive role in exploring new functional groups of microorganisms from Phlogicylindrium,Schizothecium and other microorganisms,as well as the research on the synergistic mechanism of microorganisms,and provide basic data for the research and development of biocontrol agent for lily anthracnose.关键词
